Start by writing an equation with two unknown variables
x= number of cheeseburgers
y=number of fries
![3x+2y=24](https://img.qammunity.org/2023/formulas/mathematics/college/t8ahot6gzr21ao817cohsodvk3u3r3n6zg.png)
write the equation as a linear equation
![\begin{gathered} 2y=-3x+24 \\ y=-(3)/(2)x+12 \end{gathered}](https://img.qammunity.org/2023/formulas/mathematics/college/gkea1az41ir73faptjwtgbo0c7c9kcqykq.png)
graph the equation and see all the points that lie in the line
The points with a whole solution on x and y are the possible combination Ms. Mendoza can do.
the possible combinations could be
0 hamburgers asn 12 fries.
2 hamburgers and 9 fries.
4 hamburgers and 6 fries.
6 hamburgers and 3 fries.
8 hamburgers and 0 fries.
